Engine noise? Possibly timing belt?

[lithiumionssuck]

Questions about the timing belt. Prepare for wall of text.

Not too sure what's going on in my car, ladies. I need the assistance of some of you geniuses. I'm thinking the timing belt needs to be replaced, but I'm not too sure it's that. Beyond a visual check, which would require taking half the front end off, I'm not sure what to check for.

The sound I keep hearing sounds almost like a diesel engine, just because it's kind of a dry rattle. In some of the other things I've read, I've heard that it can be something to do with the cam shaft, but I'm not too sure. I just replaced the cam follower, and the catalyst. I bought this car at 114k miles, and I now have 119k. That woukd indicate that its pretty over-due for the change. No records to be found of the timing belt being replaced, so I'm not for sure on it. Is the sound going to be related to the timing chain, something that doesn't need to be replaced, or is it something else entirely? Any help is appreciated!

Another question I have is about misfires. I've replaced all the coils, and the spark plugs as well, but I'm having misfires under load. If the timing belt is bad, is it possibly causing the misfires? Could it be bad coils again? I have no codes what so ever, and I'm beginning to get concerned about this...

Thanks again guys!

First things first. Calling people ladies(of course if they are not a lady) and asking of help isn't a great way to start a post, especially if its been covered 1000 times over and people are going to flame you. Search around more.

Second our cars have a almost diesel like sound. It is mostly normal depending how loud yours is. If there is a metal on metal sound look at the cam shaft tensioner and your cam follower.

Third. Get the timing done ASAP or you will regret it if you already are not fucked.

The misfires could be as serious as bad/broken timing/valve issues or as simple as the wrong fuel or plug gap. Hard to tell without any reference but since is only happens under load I would assume you're looking at the spark plugs or fueling issues.

I've looked on nearly 50 different websites, and couldn't find anything on this. I searched this forum inside and out, and nothing came close to what I was looking for. That's why I asked. And you'll have to excuse me if you feel this is rude, but it was kind of a humorous way to start the thread. Kind of a joke to say ladies. I'm sorry you didn't get it, but lighten up man. We're here not just for business, but for fun too.

Anyway, I replaced coils recently, but do you think that one or two could have gone out already? They were just the duralast ones after all. And at what depth can I do the plugs to make sure I'm getting good performance, and not burning through plugs? I haven't found much on depth. What do you recommend for that?

You'll want to always stick with OEM on the coils...they're already cheap enough at the dealer as it is, online is even cheaper. Same with the OEM plugs from Bosch, expect to foul out the cheap ones quicker. When's the last time you did an oil change? You'll also want to get the timing belt done REAL soon. If you have the tools and the time, there's a DIY on here that was very helpful and I was able to do mine in 2 days (taking my time and it was my first time).

when i bought my audi a year ago it had one replacement coil done, and it was a durlast. i have already had to replace it. And dont bother replacing just one, do all of them. I bought OEM ones for something like 18 bucks each.

I didnt see mention of what plug you are using. but you really need to use the correct ones, i am sure someone can chime in with the PN. They are not cheap compared to other plugs, but it makes a difference.

Depending how loud the diesel sound is it would point to your timing chain, not belt (or cam chain) the early b7's are known for the tensioner and adjusters going bad creating slop in the chain which causes it to flop up and down creating the diesel sound, there was a thread a couple months ago with like 10 different videos of everyone's car making the same noise and everyone was in agreement about what it was

Also check and change your cam follower

I changed the cam follower this week. No dice. I'll look into that chain.

Or the Serp belt tensioner

You're right have fun with those duralasts. If you have searched over 50 sites you would know that you shouldn't buy that garbage and that the "diesel" noise is how the cars run (pending your sound being normal from the rest of us) but you seem to know everything so have fun with that. Let us know when your car is scrapped due to not taking proper cautions and using shit parts.

I thought we were supposed to be on this forum to help each other, not be sarcastic dick socks.

You should probably put the timing belt kit to the top of your to-do list. At 10 years and 119,000 miles you're on borrowed time. Broken timing belt = no bueno.

Nah I am here to help people who want help. But you know everything so its cool. Ill message you if I have a question on how to change my flux capacitor or my blinker fluid. Good luck.

Dude, I'm asking questions to get answers, and find out what's wrong. You obviously don't get that. Fuck the hell off to somewhere else.

[billyhoyle]

I wasn't particularly fond of your 'ladies' and 'geniuses' comments either - they came across as a little condescending. As a new guy looking for help, you'll get a much better response if you show a little humility. Yeo has been around for quite a while, and I'm guessing he (and others) know a hell of a lot more than you do about this car.

On a positive note, 'sarcastic dick sock' gave me a good laugh.

Edit: this was buried in Yeo's first post, but the cam chain tensioner is a common source of the 'diesel' rattle. There are quite a few DIYs and discussions about that issue on here.

Don't worry about it, I'm done with this post. Good luck with your car OP.

A bag of dicks. Eat them.

[Theiceman]

ok lets get back on Track ... a few points

The belt you can inspect by removing a small triangular panel at the front of the engine ( you will see a sticker on it with your engine type and serial number I believe. ) But at that milage you are due for a change .
The belt is like high blood pressure on a car .. its a silent killer, you wont know its bad till its too late . You need to do belts rollers and tensioners and water pump now before its too late.

If your cam follower is fine its on to chain tensioner. There are lots of threads on how to remove the timing housing and inspect the tensioner. There is even an outstanding you tube video on it and he walks you through it " can you dig it ? "

good luck .." dick sock" .. that's just too funny ..

[atvhead]

dick sock LOL

[pezgoon]

Lol this got hilarious pretty quick, I didn't read the mileage but I would agree you need a belt but it's pretty easy to tell if the sound is from the front or the back, if it's from the back... well I mean unless somehow your belt runs THROUGH the engine then shit your outta luck. I agree though that I would do the belt as the change period has been upgraded to 110k so your even past that, original was 70k

If it's from the back of the car it's the cam chain/tensioner like I posted the link above.

Although I agree that his approach to the thread may not have been the best (and I had the same feelings about it) do you think the next person will read this and see that they shouldn't do it? Don't let the last ten people whom did it come out on this guy. It's a forum. It's the internet. You don't like it, walk away fro the computer (or go to another thread) and forget you even read it, everything that happened in here, not only helps nobody, but just causes 6 page flame wars that is ridiculous and ties up bandwidth.

Smoke a bowl, do some yoga, jerk it, get over it

If you read my post I just warned him that he will be flamed if he does not do the proper research and that those comments may offend people into not helping him. Then I went on to suggest several problems it could be to help him out. He in return kept the attitude so he can deal with his car without any of my help.

[aluthman]

He didn't tell everyone to put aside their douchery this time, so it's fair game.

And read this response again to your post warning about flaming, not only did he have apologize but even explained why he said it. I've been frustrated, I've been where he is and have said the exact same thing. Lighten the hell up and I reiterate, smoke a bowl do some yoga jerk it. But leave your daily bullshit behind and get over it. All our lives suck, the forum is a place to talk about things to either get help or be happy about, not to attack each other with bull shit.

It's ridiculous that this idea of flaming and attacking each other is okay in modern society. People were always idiots and retards before, now you can just see 10,000 of them a day. That shouldn't change things. Get some sense of community and get over it. Swallow your bullshit and move on. This is why I'm not on facebook and twitter and whatever else crap social media there is

And I fully agree, the searching on this site is fucking awful and returns the same stupid fifty fucking posts no matter what you type in. I get pretty tired of having to go to the fifth page to find any decent results and it has to do with lack of being able to delete bullshit posts on your own, lack of mods, and using an awful search engine. Even when I type in WORD FOR WORD the title of a post it is either last on the search page or on the next one, it is nearly impossible to find anything because of bad web keeping

WOW... this thread went to the ier fast and a hurry..........

[aluthman]

Use google to search. Just type in "Audizine A4 B7 blah blah blah" and it will give you decent results.

Use google to search. Just type in "Audizine A4 B7 blah blah blah" and it will give you decent results.

Site:{URL} narrows it down pretty quick.

"Site:audizine.com a4 b7 diesel sound" will get you a billion results with good info.

Or just click "more results from audizine.com" under the first audizine result in a regular death and it will do the same thing. Also, if you want to omit some results you can use "-(term)."

For instance, "site:audizine a4 b7 19" wheels -rotiform" will display all results that don't mention rotiform. Not the best example but you get the idea.
